I've recently installed the Vehicle mod for 1.15.2
I have the latest forge,
latest vehicle mod and obfuscate library mod.
I am missing all vehicles besides the aluminum boat; as well as the entire childhood toy section (which i have downloaded as well) are there any fixes for this, or maybe I'm doing something wrong?

any help would be appreciated, thanks.

Are they showing up in the creative tab?

Oh! yes they are, wondering why they wouldn't show up anywhere else. Thank you!
